WILLIAM A. BOND, 0F LYNN, Iv'LASSAGI-IUSETTS, ASSIGNOR 'IO UNITED SHOE MACHINERY COMPANY, OF PATER NEW JERSEY.

SON, NEW JERSEY, A CORPORATION OF BUEFIN G-MACHIN E.

To all whom it may concern:

Be it known that I, WILLIAM A. Bonn, a

citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Imtrated in connection with a machine for bufhug the soles of boots and shoes. I

In bui'ling or scouring boots and shoes it is desirable to imitate as closely as possible the hand-scouring operation in which the hand of the operator describes a series of closed curves which overlap'one upon the other. In practice, however, it has been found that a rotating roll has many'points of advantage, and the problem, therefore, has been to give to the operative surface of such a roll the desired movement. With this end in view butting rolls have been simultaneously reciprocated and rotated; but, although the compound movement thus pro duced is very effective, the, general object of the present invention is to produce a movement which approximates more closely the movement of the hand operator.

To this end, one feature ofthe present invention consists in the combination with a rotating operating member of means for moving said member in an orbital path. And by orbital path? is meant any path which returns into but not upon itself; that is, a closed path described by abocly which moves at all times in a forward direction with regard to its path as distinguished from a closed path which returns upon itself as in the case of reciprocation. In the illustrative machine the operating member takes the form of a roll which is rotated aboutits longitudinal axis; and this combined axial rota:

tion and bodily movement in an orbital path, results in a compound movement which ap proximates very closely the movement of the hand of a hand operator and produces upon the sole of the shoe a surface which takes an exceedingly satisfactory finish clure,

' the. subsequentpolishing. operation.

Application filed August 9, 1911; Serial No. 643,130.

Considered from a different aspect another feature of the invention consists in the combination with an operating member and means for rotating said member of means for moving said member in a predetermined path at an angle to its axis of rotation, this transverse movement being in the illustrative machine part of'an orbital movement referred to above.

The shoe is ordinarly presented to the roll at an angle with the toe pointing downwardly, the angle varying somewhat with the individual operator, and in the present machine the angle at which the shoe is presented'is determined by the plane of the orbital path of the roll.

Accordingly, another feature of the present invention comprises means for varying the inclination of the orbital path of the roll so that the machine may be readily adjusted to conform to the preference of the given operator.

These and other features of the invention including certain details of construction and combinations of parts will be described in connection with an illustrative machine and pointed out in the appended claims.

eferring to the accompanying drawings, Figure l is a front elevation of the machine in which the present invention is embodied; Fig. 2 is a side elevation of a portion of the machine, certain parts being shown in sec tion to illustratemore clearly the mechanism by which the journal boxes are actuated. In this figure one of the possible angular positions of the bracket is indicated in dotted lines; and Fig. 3 is a detail principally in section showing a modification of the means for compelling the roll shaft to move with not shown in the bottom of the guideways and are threaded into said guides. These guides 5 are formed on and support brackets 9 which in turn support casings 11, the lower parts of said casings in the illustrated machine, being integral with said brackets;

while'the upper parts consist of plates held, n place by means-ofscrew bolts 12. "Thelnteriors of these casings are.-rectangular-in cross section, and the upper and lower walls serve as slide bearings for the journal boxes 13, said boxes being thus movable in any horizontal direction.

The roll shaft 15 carrying the operating members 17, herein shown as buffing rolls, is rotatably mounted in the journal boxes 13 and has fast to one end a. pulley 19, to which power may be applied from any convenient source, and fast to the opposite end a pulley 21 from which power may be transmitted by means of a beltto the pulley 23 on the counter shaft 25. This counter shaft is mounted inbearings in the brackets 9 and is adapted to be swung outwardly with the brackets in the manner indicated in Fig. 2. In order to maintain the belt which passes over the pulleys 21 and 23 at a constant tension the guideways. 3 are arcs of circles struck from the center of the roll shaft 15.

The counter shaft has fast to it spiral gears 27 which mesh with similar gears 29 fast to upright shafts 31. Each shaft 31 is mounted in bearings 33 and 35 formed in the brackets 9 and has its upper end journaled. in a bearing 87 formed in the upper wall of the casing 11. Each journal box 13 is formed with an eccentric strap 39 which V encircles an eccentric 11 formed on the upper part of each upright shaft 31, each eccentric being encircled by a bushing 43. \Vith this construction a movement transverse to the axis of rctation of the shaft 15 may be imparted to the journal boxes 13, said movement in the illustrated machine being part of the orbital movement of said boxes. In order that the roll shaft 15 may partake properly of the movement of the boxes so as to be moved longitudinally of its axis as well as transversely thereto, saidshaft carries near one end a fixed collar 45 which bears against the outer end of the right hand journal box, as viewed in Fig. 1, there being at the opposite end of the shaft a loosely mounted washer 47 held against the outer end of the left hand box by means of a spring 49 which bears with one end against said washer and with the other against the pulley 19.

The eccentrics in the illustrative machine are set at the same angle and consequently the two ends of the roll shaft are in similar points of their orbits at any given moment, so that a gi en print on either roll describes a circle. The spiral gears 29, however, are

adjustably held in place'by washers 51 and nuts 53 so that by loosening one of said nuts the corresponding shaft 31, and with itthe corresponding eccentric, may be set at any desired angle. For example, let it be supposed that the eccentrics 41 are set 180 apart. The paths of any two similarly located points on the two rolls will then no longer be circles, nor will said points be in cor esponding, portions of their respective 1 paths at any given moment. The paths in this case will approximate two isosceles triangles having their apexes in proximity. It will be unnecessary to consider further specific examples of the relative angular positions at which the eccentrics may be set, but it should be noted that, if desired, one of the gears 29 may be removed whereby a movement will be imparted to the rolls which will be quite different from either of the movements referred to above. Itis thus possible to select from a great variety of possible movements of the rolls the particular movement desired. As thus far described, the plane of the orbital paths of the boxes and hence of the rolls is horizontal. The purpose of the guideways 3 and guides 5, however, is to permit the said paths to be inclined to the horizontal; and, in order to facilitate the adjustment of the bracket 9 as well as to hold it more firmly in adjusted position, slotted fingers 55 are pivoted to the brackets 9 at 57 and may be clamped to the frame in any desired position by means of the bolts 59. In case that the eccentrics are set at the same angle so that the journal boxes describe similar orbits, the spring to is not essential, and in Fig. 3 said spring has been omitted and in its place has been substituted a collar 61 fast to said shaft. It should be noted that various other arrangements of collars and springs may be used, if desired, to compel proper movement of the shaft with the boxes.

The operation of the machine is as follows: The eccentrics are set in the desired angular relation with respect to each other in the manner described; the brackets 9 are. adjusted to the desired angular position, and power is applied to the machine. The operator then presents the bottom of the sole of a boot or shoe to the under side of the rolls. The rolls, moving in the path described above, will thoroughly scour the bottom of the shoe, the only manipulation required of the operator being to present the sole of the shoe progressively to said rolls.

Although the invention has been set forth in connection with a particular machine, it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.
